Analysis
What Problems Does the 2011 Mercedes-Benz SL-Class Have?
Long-term reliability concerns often center on the aging of rubber components (seals, hoses) and the increased likelihood of electronic failures as the car gets older. The AMG models, with their higher performance engines and more complex systems, may require more frequent and costly maintenance. Owners should also be aware of potential issues with the transmission and differential, especially in higher-mileage vehicles. Regular maintenance and addressing minor issues promptly are crucial for mitigating these concerns and extending the lifespan of the vehicle.
How long will the 2011 Mercedes-Benz SL-Class last?
What Technology & Safety Features are Included?
Driver-assistance features are relatively limited compared to modern cars but include standard features like anti-lock brakes, stability control, and traction control. Safety features consist of multiple airbags, including side airbags and knee airbags. Optional features included Keyless Go, Airscarf (neck-level heating system), and park assist.
While official crash-test ratings from agencies like NHTSA and IIHS may be limited specifically for the 2011 model year, the SL-Class generally performed well in safety tests for convertibles of its era. However, it's important to note that convertible vehicles often have inherent structural differences compared to hardtop cars, which can affect crash performance. The presence of electronic stability control and advanced braking systems contributes to its safety profile.

How Does the 2011 Mercedes-Benz SL-Class Compare to Other Sedan?
Regarding reliability, the SL-Class can be less reliable than the Porsche 911, particularly concerning its ABC suspension. The Jaguar XKR shares similar potential maintenance concerns due to its complex systems. Feature-wise, the SL-Class offers a luxurious interior and a comfortable ride, but its infotainment system lags behind newer models. The BMW 6 Series might be a better alternative for buyers prioritizing advanced technology. The Porsche 911 is the superior choice for drivers who value performance and handling above all else. For someone wanting similar luxury and open-top experience with potentially lower maintenance costs, a newer Lexus LC 500 convertible (though a different generation) could be considered, but at a higher price point than a used 2011 SL-Class.

Most Beautiful Car That I Have Ever OwnecThis vehicle is the epitome of technology. Everything is designed to pamper the driver with ultimate comfort in the safest environment possible. The diamond white exterior is simply breathtaking and the interior details are absolutely amazing.

Not very comfy at 6'1I got my dream car! Finally can afford it after 5 years of depreciation! It's definitely the best convertible out there, if driven 1-2 hours at a time. Anything more than that would give me back pain. The seats are not very comfortable, and they do not lean back enough when at farthest setting from steering wheel (I've got long legs). Everything else about this car is almost perfect! The interior could be improved also, but who cares with such a sexy exterior!

SL 63 -- Truly a Gentlemans supercar2011 SL63-- when you are looking for a supercar, but dont want the stiff ride that rattles your teeth, the SL63 is the answer. 518hp, paddle shift, unbelievable get up and go, an exhaust note that will stop your heart, and all this with heated, cooled, and massage seats. Oh, did I mention an warm air scarf that blows heat on your neck on those cold days should you want the top down. All the creature comforts of a luxury car, but the absolute heart of a top end sports car. A blast to drive, reliable, and truly a grand touring hard top convertible that you can drive for hours and hours.

This is a GT, not a sports carThis car is a great cruiser with plenty of power and handling to keep it fun. If you are looking for a lively sports car, buy a Porsche, but if you are looking for a fantastic luxury sports convertible, there is no better car. This car is absolutely packed with every option you can image to make you drive pleasant. With the top down at 80mph and the windows up, there is virtually no wind in the cockpit. On cool nights, turn on the airscarf to blow warm air on your neck. The driving experience is impressive. The suspension system creates the illusion of a much lighter car when needed, but gives you that rock solid, heavy Mercedes ride always. This is no light weight machine. The V8 is smooth, but not chest-pressingly quick. Think locomotive, rather than racecar. That is not to say it is slow, but in this day and age of twin turbos, the normally aspirated SL is much more linear in the way it gets to 100mph. All that said, there are some things that Mercedes forgot in 2011. Generally speaking, the interface that houses the navigation system, radio, phone, etc is difficult and not intuitive. As well, the phone interface is maddening and the mic is noise sensitive (not a great feature in a convertible). Lastly, the gas mileage is measured in feet not miles (I average 14.7mpg to work). But, in a car that automatically turns on the air conditioned seats when you remotely put the top down and is powered by a creamy V8 mounted on a truly mind-blowing suspension, the minus fall away pretty fast. After all, this is a Mercedes SL.

MB BESTGREAT VEHICLE TO CRUISE IN TO THE BEACH WITH A WIFE OR THE GIRLFRIEND COMFORT IS GREAT HANDLING IS EVEN BETTER AND MOST IMPORTANTLY, YOU ARE MAKING A STAEMENT BY DRIVING A CAR LIKE THAT

M.B. SL550This car looks and handles beautifully. Unfortunately what M.B. refers to as "safety features" are for the companies safety and not the car owners. The convenience features are about the most inconvenient of any car I've ever owned and the navigation system would make a very expensive paper weight.
